Winchester SX4 12 Gauge Semi-Auto Shotgun 26" Barrel 3.5" Chamber

The Winchester SX4 semi-automatic shotgun delivers rapid follow-up shots and versatile performance for waterfowl hunting and upland game. This 12-gauge platform features a 26-inch barrel with 3.5-inch chamber capability, accommodating everything from light target loads to heavy magnum shells. The matte black finish provides corrosion resistance while reducing glare in field conditions.

What Makes This Different

The SX4's Active Valve gas system automatically adjusts to different shell pressures, cycling reliably with both light 2.75-inch loads and powerful 3.5-inch magnums without manual adjustment. The chrome-plated bore and chamber resist corrosion from moisture and fouling better than standard steel surfaces. Winchester's Invector-Plus choke system provides more consistent patterns than basic choke tubes, with three included chokes covering most hunting scenarios.

Key Features

• Active Valve gas system cycles 2.75", 3", and 3.5" shells automatically
• 26-inch barrel optimizes velocity for waterfowl and upland hunting
• 4+1 capacity with drop-out trigger group for easy cleaning
• Chrome-plated bore and chamber for corrosion resistance
• Three Invector-Plus chokes included (Full, Modified, Improved Cylinder)
• Matte black synthetic stock resists weather and impacts
• Crossbolt safety located behind trigger guard

Field testing shows the SX4 cycles consistently in temperatures from -20°F to 120°F, making it suitable for early-season dove hunting through late-season waterfowl pursuits. The 26-inch barrel length balances swing characteristics for crossing shots while maintaining enough length for complete powder burn with magnum loads. The synthetic stock material won't warp or crack in wet conditions that damage wood stocks.
